Information is collected as evidence. It contains facts and data.
Then again, what really is scientific proof?
Empirical evidence is what is employed by scientists.
This is proof that has been obtained directly through observations and measurements. The two basic categories of empirical evidence are qualitative and quantitative.
Observations are used to obtain qualitative evidence, which is then reported through written descriptions of the characteristics of the observations.
The gathering of quantitative evidence involves measurement and computation. It entails figuring out quantities or quantities and sizes. Numbers or amounts are used to describe this type of information.

Darwin was influenced by many other scientists including the economist Malthus, who studied population size. Based on Malthus’ research, what did Darwin infer about why natural selection is a result of overpopulation? (Overpopulation: Too many animals)
a. When there was overpopulation, there were too many different species in one area.
b. When there was overpopulation, there was more food than is needed by a population.
c. When there was overpopulation, there were too few organisms to enable all to survive.
d. When there was overpopulation, there were more offspring than the environment could support.
Answers
Based on Malthus’ research, Darwin indicated that the process of natural selection is a result of overpopulation because d. When there was overpopulation, there were more offspring than the environment could support.
What is Darwin's evolutionary theory of natural selection?Darwin's evolutionary theory of natural selection makes reference to the differential survival and reproduction rate of the most adapted phenotypes in a given environmental condition, which depends on the maximization of the available resources for this environment.
Moreover, Thomas Malthus developed the so-called Malthusian model of growth, which indicates that food production may not be enough to keep up with the growth of a given population of people.
Therefore, with this data, we can see that Darwin's evolutionary theory of natural selection is based on the existence of limited resources and the competence between the organisms for such resources in particular environmental conditions and factors.

The seed formed inside the ovary of the flower. As the seed develops in the flower, water is withdrawn from it so that it becomes almost dry. suggest why is it important?
Answers
Water withdrawal from the developing seed inside the flower is important to induce dormancy, enhance longevity, protect against pathogens, facilitate dispersal, and trigger germination under favorable conditions.
Water withdrawal from the seed during its development inside the ovary is crucial for seed dormancy, longevity, protection, dispersal, and germination. Dormancy enables seeds to survive unfavorable conditions. The dry state reduces metabolic activity, enhancing seed longevity. Withdrawing water creates an inhospitable environment for pathogens, safeguarding the seed. Dry seeds are lighter and more easily dispersed by wind, animals, or water, aiding in the colonization of new habitats. Rehydration of the seed after dispersal triggers germination, initiating growth.Overall, water withdrawal from the seed inside the ovary serves as a survival strategy, allowing seeds to endure harsh conditions, remain viable for extended periods, avoid microbial damage, disperse effectively, and germinate when conditions are favorable.

E. In 7 years, 1000 children suffered from anemia.
Answers
A study showed that morbidity of children with anemia was 7:1000. This means that (B) 7 children out of 1000 had anemia or suffered from anemia.
The study showed that morbidity of children with anemia was 7:1000. The term "morbidity" refers to the incidence of a disease or the prevalence of a condition. The ratio 7:1000 indicates that for every 1000 children, 7 of them had anemia or suffered from anemia. This means that 0.7% of the children in the study had anemia.
However, it does not mean that 7 children out of 1000 died of anemia or that they recovered from blood-borne pathogens. It simply means that 7 out of 1000 children had anemia. Morbidity is often used in public health to determine the incidence of a disease and to track its prevalence over time. It is a useful indicator of the health of a population, as it can help public health officials to identify trends and develop strategies to prevent and treat diseases.
In conclusion, the study showed that 7 children out of 1000 had anemia or suffered from anemia. The correct answer is B.

Answers
Answer:
D. Warmed air sinks is not a normal convection cycle outcome
Explanation:
Warm air is buoyant and rises. Cold air is dense and sinks.
Think of fog in the air. Fog forms in low/cool areas, as the sun comes out and warms up the atmosphere the upper atmosphere, heat flows to cold so upper atmosphere air displaces the fog.
Space heating, the steam or hot water radiators are placed along the floor typically causing convection of warm air to rise up over windows and cold walls, breaking up cold air drafts.

How does a decrease in abiotic resources impact the population growth in an ecosystem?
A. The population size will increase
B. The population size will decrease
C. The population size will not change
Answers
Answer:
B. The population size will decrease
Explanation:
Abiotic factors may include temperature, sunlight and water. If conditions are too cold for the organisms living there, they may perish. If the amount of sunlight decreases, plants will not be able to produce enough glucose through photosynthesis. If the amount of water decreases plants may bot have enough water to photosynthesise and animals will have to compete for water.
Temperature, sunlight, and water are abiotic. Organisms may die in frigid environments. Therefore, option (B) is correct answer.
What are abiotic resources?Abiotic and biotic environmental factors fall into the category of population-influencing factors. The non-living physical and chemical components that make up an ecosystem, such as temperature, pH, sunlight, shelter, and day length, are referred to as abiotic variables.
Cold conditions can cause the death of organisms. If sunlight dwindles, photosynthesis cannot produce enough glucose. Lack of water may make it difficult for plants to photosynthesize, forcing animals to compete for it.

Through the process of cellular respiration, organisms mix oxygen with food molecules, directing the chemical energy contained in these substances toward life-sustaining processes while excreting carbon dioxide and water as waste.
Foods are broken down by organisms that do not require oxygen in a process known as fermentation. (For more in-depth discussions of various cellular respiration topics, see tricarboxylic acid cycle and metabolism.)
Adenosine triphosphate (ATP), an energy-rich compound that absorbs the chemical energy obtained from the breakdown of food molecules and releases it to power other cellular processes, is one goal of the degradation of foodstuffs.
